Ari is absolutely amazing! My skin has completely transformed since seeing her it’s now clear, glowy, and the healthiest it’s ever looked. She’s so approachable and kind, and really takes the time to listen to your concerns. I love that she never pushes expensive products or unnecessary treatments and she truly cares about what’s best for your skin. Every appointment feels relaxing and personalized. I can’t recommend Ari enough if you’re looking for someone who genuinely wants to help you achieve your best skin!

Went here for laser hair removal, was super nervous because I had little to no knowledge about the process. Thankfully Ariana De Jesus (Ari) was very informative and understanding which helped me relax. I hardly had to ask any questions because she was very detailed about the process and after care. Thanks to her, I had an overall good experience. I definitely recommend this place because of her.

The aesthetician, Ari, is amazing! She is extremely professional, and somehow at the same time makes you feel like you have been friends forever! She really listened to what my skin concerns are and answered my questions thoughtfully. She is the reason I get so many compliments on my skin! Would recommend Ari to anyone!

I have been seeing Ari for a few years now and she has helped so much with my skin. Having rosacea my skin is extremely reactive. She has curated the perfect combination of treatments and products. She actually takes the time to explain the purpose/technology of each treatment as well as ingredients in products. Highly recommend her as your skincare provider!

I had otoplasty done by resident Dr. Lauren Conner in 2020 or 2021, during covid. Dr. Conner went above and beyond and I am forever grateful. Not only is she a complete professional but she understood that my surgery wasn't just about the physical part of my situation. I think about her alot and pray that she is well. Thank you so much Dr. Conner, I wish you the best always.
